Screw-retained

Dr. Eitan Krause, Oral Rehabilitation Specialist & Dr. Amir Schuster, Mouth and Jaw Surgery Specialist.
Computerized planning of implant-supported rehabilitation and implant insertion with bone-supported splint using ABGuidedService software, as demonstrated in this patient, allowed precise positioning of implant with full synchronization between bone structure and patient’s existing teeth. Bone-supported surgical splint resting passively and accurately on top of bone tissue allowed drilling and implant insertion according to the location, angle and depth established during the planning stage. Temporary acrylic permanent partial dentures, previously planned according to intended implant location and attached to implants after their insertion into the bone with temporary structures (immediate loading), allowed patient to regain full aural functioning.

A.

Patient (F, 62) complained of complete loss of retention of a partial fixed denture (13-25) due to widespread dental caries of the holding teeth

B.

CT scans show massive metallic substances (large number of dental implants, a large metal-based bridge, a wide bar supporting a removable denture) are affected by “noise” that blurs osseous elements

C.

Implants were planned based on the CT scan

D.

Impressions were made to create lab acrylic permanent partial dentures combined with an acrylic base resting on the gum

E.

The surgical procedure itself was performed using a bone-supported surgical splint

F.

After the flap lift and teeth extraction, the surgical splint\'s compatibility with the bone tissue for definite passive imposition was examined

G.

The splint was attached to the bone tissue with fastening screws

H.

The bores in the bone for positioning the implants were made with a set of drills dedicated for use with surgical splints (AB Guided Drill Kit)

I.

The insertion of the implants into the bone was also guided by the surgical splint

J.

Insertion of the implants to the predetermined depth using dedicated stoppers. Scale marks on the stopper accurately indicate the depth of the implant screw

K.

Upon completion of inserting the implant, they were attached to temporary structures of types P15 and P12

L.

Upon completion of inserting the implant, they were attached to temporary structures of types P15 and P12

M.

The acrylic permanent partial denture placed upon the implants precisely at the predetermined position and helped by covering the acrylic palate.

N.

The acrylic support on the palate was removed and the bridge was processed to create a screwed/glued acrylic permanent partial denture
